The only clear and definitive answer we could give you is that there is no
clear and definitive answer.
Adobe and Microsoft are playing a silly game of "our way or the highway"
that leads to huge problems.
Word v.X needs to come out of the equation, it does not have the ability to
handle any kind of vector graphics properly (it tries to create QuickDraw
things which which work somewhat badly on everything except an old Mac).
WMF should be a lot better, but it depends on how it is made. Illustrator
is determined to create them with a TIFF preview. To keep it small, it's a
VERY low-resolution and it will look like a smudged postage stamp. Sadly,
most flavours of Mac Word are unable to find the "vector" component of the
image and they tend to print the preview (it's a bug...)
I avoid this by making a WMF with a WMF preview, which looks nearly as good
as EPS. But I don't think Adobe allows this (because to do so would enable
Microsoft software to produce high-quality graphics...)
WMF will never be as good as EPS because a WMF is composed of a large number
of short, straight lines. Curves lose quite a bit of resolution as a
result. But most software can handle it.
EMF will look a lot better if it is properly created, because it contains
real curves and it also has a 24-bit colour table. But I suspect Adobe
creates its EMF using a fairly coarse conversion filter, because it doesn't
seem to work that well. Again, the Adobe preview is in TIFF, and old
versions of Mac Word tend to lose the vector information and print the
preview instead (bug...)
EMF is a format you might persist with for cross-platform work, because on
the PC it looks perfect and it does not require a PostScript interpreter on
the printer. But it's important NOT to create a preview with your EMF
image, because if you do, that's what most versions of Mac Word will print
{Sigh...} And some versions of Mac Word can't display the EMF if it doesn't
have a preview {it's a bug...}
EPS should look perfect, but Microsoft software has not been able to get EPS
right on the Mac until Office 2008. Microsoft was trying to make Adobe look
bad...
Matt is quite correct: high-res PNG is safe in any Microsoft application.
But it adds a lot of weight to the document (it's about twice the size of
JPG).
PNG uses 24-bit colour and retains full resolution at the expense of colour.
JPG retains the full colour table and sacrifices resolution to preserve
colour. JPEG consequently works well for photos, PNG works well for stuff
where resolution is important.
Until Microsoft and Adobe stop this silly game, graphics in Microsoft Office
for the Mac will remain a problem.
I just tested the following formats in Word 2008 version 12.1.7 in .docx
format, using Insert>Picture>From file...
EPS with WMF Header
EPS with TIFF Header
WMF with no Header
WMF with WMF Header
EMF with no Header
PNG at 300 dpi
I got excellent results with each one. Some notes:
* EPS really does work properly at last: full resolution curves, proper
line weights, fountain fills work properly, the whole enchilada.
* EPS with a TIFF Header worked just as well! Mac Word 2008 seems to have
solved its issue with printing the header instead of the vector information.
* WMF works really well, but if you include small sharp curves you WILL see
the difference at high magnifications. The graphic I made to test this was
looking for aliasing effects and I found them. But an office worker looking
at a half-page graphic at 100 per cent zoom probably won't see them. Some
of the line weights will change, some of the curves will get a little rough,
and the fountain fills suffer "stepping" at high magnifications. But that's
a limitation of the 8-bit WMF format.
* WMF with no header looks just as good/bad as WMF with a WMF header.
* EMF is twice as good as WMF, nearly the same as EPS. That's a legacy of
EMF's 24-bit colour table and the 32-bit vector numbers: everything will be
a lot more accurate.
* PNG looks good (at 300 dpi it would want to...). I got a colour shift
because I chose a CMYK colour conversion and I was too lazy to go back and
change it. If you wish to succeed with Microsoft applications on a PC,
stick to 24-bit RGB or you will get problems.
* The method you use to insert the graphics makes a difference.
Insert>Picture>From File... Will give the best results. Avoid "Paste" like
the plague, you never know what will actually land in the document!
So: I now have confidence in saying that Microsoft seems to have finally
solved its problems with Word 2008's vector graphics.
However, it is important to work in .docx. Not least because the .docx
format stores the original graphics in their original format! When I opened
up the .docx by unzipping, I found the image in there as a PDF and a PNG
pair for the two EPS versions. The EMF is stored as an EMF. The WMF as a
WMF, and the PNG as a PNG.
Saving in the old .doc format still gives good results in Word 2008 (but
don't bet on it with complex high-res graphics) but the file size blew out
from 380 kb to 800 kb. You need to expect that because the .doc format
would contain down-converted versions of each graphic. This document
contains almost nothing but the test graphics.
Sorry: No good answers...
Hope this helps

Hi, I've been searching everywhere for CLEAR and definitive answers on what
file types to best create for Word to import. It is surprisingly hard to get
cold hard facts on this!
So this is what we have:
Simple letterhead header & footer that need to be placed in Word templates.
Files are created in Illustrator (CS3), and are simple logo & text, though all
text has been converted to curves, and all colors are RGB.
This is what I've tried:
- EPS: Seems most obvious, and if you have a postscript printer everything
goes pretty well. Screen graphics look poor, though, as does printing to
non-postscript printer.
- EMF: Created from Illustrator. Printed really poorly (almost like a smudged
stamp).
- WMF: Definitely lower quality than EPS.
- PNG: Created 600dpi PNG file to avoid postscript issues. PNG files were
small (less than 150k each). But after embedding PNG and saving Word file, it
balloons to over 5Mb! Linking files is probably too dangerous for this client.
??? What is the BEST and most solid format to use for vector files coming into
Word???
I also learned that Word has changed their EPS import filters between Word
2003 & 2007, so that confuses things even more. We have 2003.
THANKS!!!
